Model is as follows:

class Shop < ActiveRecord::Base

validates_presence_of :title, :url, :description, :message => "can't be blank"
acts_as_url_param :handle, :from => :title, :on => :create

end

Rails 2.3.3 on MRI Ruby 1.8.7

Not sure if there are plans to update this for Rails 2.3. Figured I would report it just in case.

Thanks!
